PR 21384, --dynamic-list regression with f02cb058

The commit to "Always descend into output section statements in
lang_do_assignments" meant that linker script symbols were not
bfd_link_hash_new when ld called bfd_elf_record_link_assignment.
This patch corrects that problem by testing h->non_elf instead.

	PR 21384
	* elflink.c (bfd_elf_link_mark_dynamic_symbol): Test h->non_elf
	rather than h->root.type == bfd_link_hash_new.
	(bfd_elf_record_link_assignment): Similarly, call
	bfd_elf_link_mark_dynamic_symbol when h->non_elf.
